Title: Improvements in or relating to multiple filter assembly apparatus and method
Inventor: HAGAN MICHAEL BONIFACE
IPC: A24D3/02
Filed: 1967-10-03
Abstract: 1,146,259. Multiple tobacco smoke filters. BROWN & WILLIAMSON TOBACCO CORP. 3 Oct., 1967, No. 45057/67. Heading A2C. In an apparatus for the in-line assembly of components of at least three different characters to form composite cigarette mouthpiece rods each of which is divisible into mouthpieces having at least three filter sections, the three components 44, 48, 50 are fed by feeding stations 38, 40, 42 on to a suction conveyer band 78 travelling at a predetermined speed, the first and second components 44, 48 being fed at their respective stations 38, 40 at half said predetermined speed and the third component being fed at station 42 at the said predetermined speed. The feeding stations 38, 42 are constructed in similar manner to those present in the Molins D.A.P.T.C. machine (disclosed in Specification 915,203) but the station 40 differs in the construction and operation of its disc feeder 76. The feeder 76 includes cam actuated retractable fingers (84) that retract as soon as they have delivered a component 48 on to the band 78 so as to clear the plugs 44 passing it. The components 44, 48, 50 are subsequently abutted, wrapped and the continuous rod so formed is cut off in conventional manner to form quadruple length mouthpieces. As exemplified, the components 44, 48, 50 comprise double length paper, cellulose acetate and single length bonded charcoal elements respectively, the continuous rod formed being cut off through the centre of alternate double length components 44 to produce the quadruple length mouthpieces. The quadruple mouthpiece is then bisected through the now centrally placed double length component 44 to form double length mouthpieces each containing a paper element (20) on each end, two bonded charcoal elements 50 and a double length cellulose acetate component 48 in the centre. The double length mouthpieces are then united with two cigarettes and the resultant double length cigarette bisected through the centre of the remaining double length component 48 in conventional manner to form cigarettes having a three component filter mouthpiece. Other suitable granular material specified for the component 50 are alumina and silica gel.

Abstract: 1481628 Controlling light MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 21 Oct 1974 [19 Oct 1973] 45508/74 Heading G2F [Also in Division H1] A liquid crystal display panel comprises a flat substrate 10 e.g. of alumina or forsterite ceramic on which a plural series of conductors 11 terminating in other conductors 12 are formed as thick films by depositing a conductive paste e.g. of silver and glass frit in the appropriate pattern, e.g. by screen printing and heating to sinter. Thereafter an insulant glass layer 13 in which a pigment e.g. black is embodied is deposited over the conductors e.g. by applying e.g. by screen printing a mixture of glass frit, an organic binder, and an organic solvent to define a required pattern, and thereafter heating to sinter. Conductors 11 are connected to respective electrode segments 14, and through holes are left in the glass layer to expose parts of the conductors 11 to permit connections to be made therethrough, and segments 14 to be deposited therein by conductive paste subsequently heated to sinter.

Abstract: 456,980. Jet propulsion of ships. WHITTLE, F., Blackamoors, Harston Road, Trumpington, Cambridgeshire. May 18, 1935, No. 14575. [Class 114] In a jet propulsion system of the kind in which air is taken into the system compressed, heated, partially expanded in a turbine which drives a compressor and then expelled rearwardly to provide a propelling thrust, the compressor is provided with two air intakes, one on each side of the plane of the rotation thereof, the mouth of the nozzle of the turbine extends substantially entirely around the periphery of the turbine rotor, and the outlet from the compressor is connected to the inlet to the turbine by a continuously smooth passage which constitutes a secondary diffuser for the compressor and a combustion chamber for the heating device. The compressor comprises an impeller 10 in a casing 12 and its shaft is formed in two parts 14 and 15 on which is formed a flange 16 by which it is attached to the boss of the impeller. Shaft portion 15 also constitutes the shaft for the turbine 17 which has a supply duct 19 of volute form. The impeller discharges into a primary diffuser 21 which in turn discharges into a scroll 22 to which is connected at its largest part a helical combustion chamber 24. The discharge from this chamber is of tapering form and passes to a rotor. The chamber 24 contains means for heating the air flowing through it such as a fuel jet 25. The supply to the turbine rotor is constituted by a continuous ring around it and the air then passes into an annular chamber 29 which merges into a fore-and-aft conduit 30. The compressor is attached to the body of the craft by lugs 35 projecting radially which engage strengthening members 36 running fore-and-aft inside the body. Specifications 347,206 and 456,976, [Group XXVI], are referred to. According to the Provisional Specification, means for governing and controlling the unit include a variation of the fuel supply accompanied by automatic speed regulation as by means of centrifugal governor and this governor may operate upon a piston relay valve of a servo system. It is also stated that an auxiliary compressor for the supply of compressed air to a cylindrical cockpit for breathing purposes at high altitude may be employed.

Title: Method of manufacturing heaters for electron tubes

Abstract: 1,034,990. Making heaters for electron tubes; coiling. RADIO CORPORATION OF AMERICA. Nov. 23, 1964 [Dec. 30, 1963], No. 47537/64. Headings B3A and B3E. A method of making heaters for electron tubes comprises winding a wire on a mandrel, winding the wire wound into a helix and separating the turns of the helix from one another to form a plurality of shaped heater workpieces. As described, tungsten wire is wound on to a molybdenum mandrel and the wire wound mandrel is wound helically on to two spaced parallel support rods, one having a larger diameter than the other to produce a helix having triangular turns. The two support rods are rotated and moved axially and the turns of the helix are secured to the larger rod by notching the rod and closing the notches. The smaller rod is then removed leaving the helix attached to the larger rod which may be annealed by firing at 800‹ C. in a hydrogen atmosphere. The supporting rod may be bowed on leaving the winding apparatus and this bow is removed by stretching the rod and applying a reverse bow. The helix is then coated with insulating material, e.g. aluminium oxide, by dipping the turns of the helix into a bath of insulating material, leaving the region of the helix adjacent the rod uncoated. The individual terms are then cut from the rod and the molybdenum mandrel is dissolved using a mixture of sulphuric and nitric acids to produce a heater consisting of a V-shaped coil which is coated with insulating material except for the end portions.
